I've used many cheat happens trainers by far dmc4 was the only one without errors nor crashes. Now some games I played if I saved the game while using or if I used the trainer as in config.ini has been changed the game would crash. So this one crashed for me & it didn't crash except about after 1h so what I wanna know is if I save will that make the game crash even if I didn't use it because in some games it did happen so I uninstalled the game!!!
